All All All Harmful Advice

The book includes the most well-known harmful advice from all four books of Harmful Advice with illustrations by Andrey Martynov. Grigory Oster tells how decent children should behave at home, at school, on the street, in transport, and in other public places in the genre of harmful advice that he invented himself. The writer suggests doing a lot of foolish things and assessing the consequences when the adults come. But this is, of course, only for those children who lack a sense of humor. And there are no such children in the world! For younger school age.
